OAKLAND, Calif., June 13 (UPI) -- Girls ages 9-12 with higher levels of bisphenol-A in their urine had twice the risk of being obese than girls with lower BPA levels, U.S. researchers say.
Principal investigator Dr. De-Kun Li, a reproductive and perinatal epidemiologist at the Kaiser Permanente Division of Research in Oakland, Calif., said BPA is used to make plastics and other materials, such as cash register receipts. It is a known as an endocrine disruptor and in children and adolescents, BPA is likely to enter the body primarily through the ingestion of foods and liquids, Li said.
